Abstract: A tongue jack includes a drive screw and a lifting assembly coupled with the drive screw. A first bevel gear is secured to the drive screw with a rotation axis aligned with a rotation axis of the drive screw. A second bevel gear engages the first bevel gear with a rotation axis perpendicular to the rotation axis of the first bevel gear. A drive head is connected to the second bevel gear, and a coupler is selectively engageable with and disengageable from the drive head. A handle assembly may be connected to the coupler that is rotatable about the rotation axis of the second bevel gear, where the handle assembly includes a crank handle spaced from and parallel to the rotation axis of the second bevel gear.

Abstract: A strut bar having single or multi-cross member each with downward diagonally disposed extensions terminating at a pivot point and a mounting member. The mounting members are adapted to fit directly over existing shock towers and strut towers using the studs of each respective tower. A diagonally disposed support brace is connected to the cross members and to the downward extensions according greater structural support.

Abstract: This invention directs to an optical disc assembly configured to receive an analyte which can be detected by a standard optical disc reader or an optical disc reader modified therefrom. The optical disc assembly may preferably be designed so that the optical disc reader can track the disc and detect the analyte concurrently and discriminably. The optical disc assembly contains or encodes optically readable features which are trackable by the optical disc reader and which have encoded speed information enabling the optical disc reader to rotate the optical disc assembly at a determinable speed. The optical disc assembly also includes an analyte section capable of receiving the analyte that can be detected by the optical disc reader.

Abstract: This invention relates to optical discs that preferably include multiple data layers and are configured to receive analytes which can be detected by an optical disc reader. The optical disc reader may be a standard optical disc reader or an optical disc reader modified therefrom. The optical disc may include (1) a first layer including optically readable structures which have encoded tracking information, and speed information enabling an optical disc reader to rotate the optical disc at a speed that is determinable from the speed information; (2) a second layer including optically readable structures; and (3) an analyte section capable of receiving an analyte which can be read by the optical disc reader.

Abstract: A process for chemically treating a metallic part such as a part used in aerospace applications comprising providing a process tank capable of receiving at least one part; providing at least one part to the process tank; providing an alkaline first solution into the process tank from a first storage tank; providing the first solution from the process tank into a transition tank; providing water to the process tank; providing the first solution from the transition tank into the first storage tank; providing an acidic second solution into the process tank from a second storage tank; providing the second solution into the transition tank; providing water to the process tank; providing the second solution into the second storage tank; providing a third coating solution having a pH of about 1.0 to about 3.0 into the process tank from a third storage tank; providing the third solution into the transition tank; providing water to the process tank; and providing the third solution into the third storage tank.
